University IT Warns Against Upgrading to MacOS 10.14 Mojave

September 19, 2018

Apple’s newest OS, Mojave is scheduled for release on Monday, 9.24.18. The University’s antivirus/anti-malware, CylancePROTECT is not currently compatible with Mojave until a newer version of the product is released; currently scheduled for late October. Following deployment of the new version of CylancePROTECT, the University’s systems will undergo testing to ensure all major system compatibilities. See below for the official notification from Cylance Support.

** PLEASE NOTE:A follow-up notice will be posted and sent to users when this is completed.

What Happens If You Install Mojave?

Installation can cause the machine to become unresponsive and unusable.

What: The macOS CylancePROTECT Agents version 1494 and lower are not compatible with macOS 10.14 (Mojave). Systems running macOS 10.14 and Agent 1494 (or lower) will experience a deadlock.

During testing and evaluation of CylancePROTECT for the upcoming macOS 10.14 release, Cylance found a change in the libraries that CylancePROTECT uses to integrate into the operating system. This change can cause a deadlock in the operating system.

When: macOS Mojave is scheduled to be released on Monday, September 24, 2018.

Affects: macOS CylancePROTECT Agents version 1494 and lower.

Recommendation: Do not upgrade systems to macOS 10.14 until CylancePROTECT Agent 1500 is released.

CylancePROTECT Agent 1500 is scheduled to be Generally Available (GA) in late October 2018.
